Okay,
Here it is. Final design! cannot be defeated, no gunsmithing, no permanent changes, cannot be torn away from the rifle, is steel and Aluminum, and will be offered for 9mm and .40 S&W.

It can be installed on either side, but you will need to order side, and caliber. It can be flipped to the other side, but it would change the caliber it works for... Odd I know but I can explain later.

On the machines this week, in finishing this week, available at dealers by end of next week we hope!
